Well, agreeing with Wayne about saving batteries isn't a good reason for voting
"no" (just to screw your fellow competitors). I was just re-emphasizing what
Calum said in an earlier post,
"Yeah, sure you do. I won't take the excuse you can't afford the batteries,
that's too lame. But if there's a good excuse, ie, you need the power/current,
then that's another story.
Bruce and you complain about AC power every contest. What do Derek, JohnG,
Ivan, Iain think?
What if someone built a robot that drove over to your side and cleaned out
behind the net so to speak and picked up any good bricks on your side back over
to its side? Wouldn't an AC power harness screw that up?"
on the "No" side, Rob Stehlik says that even though he does not have an RCX
1.0, battery power might actually have an advantage.
"For project X the
energizer titaniums bought me an extra four seconds :)"
I don't know the actual increase in speed between battery power vs
external power... ie which one is faster, etc. So his statement isn't really
an endorsement one way or another.
And in his posting on the discussion (same post),
http://news.lugnet.com/org/ca/rtltoronto/?n=8728, he makes the same "stationary
assumption". So is it because I brought it back up that I
am making the assumption, or is it because I am not a robot guy??? Most of what
I've said has been previously said, without any negativity directed towards
them.
Let's view this another way. Let's say there is a multi-RCX solution. Then
the entry has a ton of motors on it. Would this not drain the batteries?
Of course. So if you wanted to continue to compete you would need additional
batteries, and take time out to install your firmware and your programs.
Which would might make your robot unable to compete "at a moments notice".
The alternate view on this is that the general consensus could be build a
smarter design that allows alternate sources of kinetic energy...ie multi-geared
assemblies, pneumatics, battery boxes, etc.
just trying to bring some rationale either way on the issue.
